SIDNEY L. STILES, OF YVATSEKA, ILLINOIS.

H-ING E.

SPECIFICATION forming part of Letters Patent No. 406,242, dated. July 2, 1889. Application filed February 15, 1889. Serial No. 299,962. (No model.)

To all whom it may concern.-

Be it known that I, SIDNEY L. SrrLEs, of \Vatseka, in the county of Iroquois and State of Illinois, have invented a new and useful Improvement inH-inges, of which the following is a specification.

My invention is in the nature of an improvement in that 'class of hinges in which one leaf in being opened rises over an incline or cam surface on the other, so that the weight of the shutter, door, or gate will tend to automatically close the same.

My invent-ion consists in the peculiar construction of the pintle or hinge-pin in combination with a friction-roller and its journal, whereby the latteris more strongly braced as the friction-roller rises over the cam, as will be hereinafter fully described.

Figure 1 is a side elevation of the hinge open. Fig. 2 is a side elevation of the hinge,

closed. Fig. 3 is a side View of the pintle or hinge-pin; Fig. 4, a detail, in perspective of the bracket which carries the frictionroller.

Referring to the detailed part of the hinge, a a designate its two leaves or wings; a and a the respective sleeves of the wings a a; a the hinge-pin or pintle; a and a, the fixed and removable heads, respectively, of pin a a a longitudinal groove in hingepin a a a screw-thread for the purpose of securing tothe pin a its adjustable head a, which is fitted with a corresponding interior screw-thread; a the roller-bracket; a", the roller journal or spindle; a the roller. The sleeves a and a are tubular in form, and open at the ends for the passage through them of the hinge-pin a The top end of the hinge-sleeve a is finished with an inclined plane of required angle, except at its highest point I), which is finished in a plane at right angles to the axis of the sleeve, and

in such manner as to form a resting-pointv for the hinge-roller a The other and lower end of the hinge-sleeve a and both ends of the hinge-sleeves a are also finished in a plane at right angles to the axis of said hingesleeves.

Secured to one of the Wings a at such a point and in such manner as to cause it to bear upon the top of the hinge-sleeve a is travel of the roller.

the roller (1 The manner of its connection with the wing a is by the bracket a riveted to the wing; but the roller maybe secured by any Well-known means which will permit it to rest immediately upon the top rim of the hinge-sleeve a.

The two hinge-sleeves, being placed with their tubes in line with the sleeves a,between the sleeves ta as in Figs. 1 and 2, are connected by the hinge-pin a so adjusted that its groove a shall pass over the projecting end of the roller-spindle a which latter shall rest at the point (l, or at the top end of the groove a. Thus the top end of the said groove forms a bearing for the inner and projecting end of the roller-spindle a", holding it firmly against vibration during the Thescrew-cap a is now fitted into place, as in Figs. 1 and 2, thus securing the hinge-pin a in position, and so retaining it. The hinge is now ready for use. The left-hand wing a, being stationary, if the right wing is moved from the position in Fig. 1, so that the roller passes off from its point of rest at b, the hinge will close by the operation of its own weight, causing the passage of the hinge-roller (d around on the top of sleeve a from point I) to point 0, being down the incline, at which latter point it closes the hinge, as in Fig. 2. It, now, the hinge is opened to any extent short of that shown in Fig. 1, the hinge will close automatically, as aforesaid.

Having thus described my invention, what I claim as new is The autoinatically-olosing hinge herein described, oonsisting of the two wings or leaves having tubular sleeves, one of which is made with an inclined upper edge, a spindle or journal attaehed to the other wing or leaf and bearing a friction-roller resting upon the incline, and a detachable pintle or hinge-pin having a longitudinal slot in the same receiving the end of the journal of the frictionroller, substantially as and for the purpose described.
